Frame parameters specify frame sizes in character units. On
graphical displays, the
default face determines the actual
pixel sizes of these character units (see Face Attributes).
The height of the frame contents, in characters. (To get the height in
frame-pixel-height; see Size and Position.)
The width of the frame contents, in characters. (To get the width in
frame-pixel-width; see Size and Position.)
This does for the size parameters
user-position parameter (see user-position) does for the position parameters
Specify that width, height or both shall be maximized. The value
fullwidth specifies that width shall be as wide as possible.
fullheight specifies that height shall be as tall as
possible. The value
fullboth specifies that both the width and
the height shall be set to the size of the screen. The value
maximized specifies that the frame shall be maximized. The
fullboth is that the
former can still be resized by dragging window manager decorations
with the mouse, while the latter really covers the whole screen and
does not allow resizing by mouse dragging.
With some window managers you may have to customize the variable
frame-resize-pixelwise to a non-
nil value in order to make
a frame appear “maximized” or “fullscreen”.
